TECHNICAL FIELD

[0001] The present invention relates to an external storage device unit having an external storage device built in a main body casing of an information processor, the information processor having this external storage device unit, and a cover device for a storing opening of the external memory unit

BACKGROUND OF THE INVENTION

[0002] It is desirable that an external storage device is built in an information processor such as a game machine, etc. to temporarily store a game status, etc.

[0003] An external connection connector is normally arranged in a predetermined place in the external storage device. When the information processor capable of building in such an external storage device is designed, it is necessary to secure a space for storing a connector connected to the external connection connector of the external storage device, and wiring extending from this connector in addition to the external storage device within the main body casing of the information processor.

[0004] As mentioned above, since the external connection connector of the external storage device is arranged in a predetermined place of the external storage device, its wiring is also regulated in a position of the external connection connector. Therefore, design of the storing space within the main body casing is greatly regulated to secure this wiring space and the storing space of the connector connected to the external connection connector. Accordingly, a problem exists in that the main body casing is large-sized and the design of the main body casing, etc. are unavoidably changed in a certain case.

DISCLOSURE OF THE INVENTION

[0005] In view of such a problem, an object of the present invention is to provide an external storage device unit capable of securing the degree of freedom of the position of wiring from the external storage device and avoiding a large-sized structure of the main body casing of an information processor and the change in design of the main body casing, etc., and the information processor having this external storage device unit, and a cover device for a storing opening of the external storage device.

[0006] Therefore, the external storage device unit for achieving the above object is an external storage device unit in which an external storage device having an external connection connector is arranged and is built in a main body casing of an information processor from an opening of this main body casing, said external storage device unit comprising:

[0007] a cover for blocking the opening of said main body casing,

[0008] a storage device side connector attached to one face side of said cover, and connected to said external connection connector;

[0009] a main body side connector attached to said one face side of said cover; and

[0010] wiring for electrically connecting said connector for a storage device side and said connector for a main body side.

[0011] Further, the information processor for achieving the above object is characterized by comprising:

[0012] said external storage device unit;

[0013] said main body casing for storing said external storage device of said external storage device unit; and

[0014] a main body connector for a cover side arranged within said main body casing, and connected to a main body side connector attached to said cover.

[0015] In accordance with the invention mentioned above, since the connector for a storage device side connected to the external connection connector of the external storage device is arranged in the cover for blocking the opening of the main body casing, it is not necessary to secure a space for storing this connector for a storage device side within the main body casing. Further, the position of wiring for connecting the device main body and the external storage device can be freely changed by suitably setting a position of the connector for a main body side arranged in the cover, in other words, by suitably setting the cover side main body connector connected to this connector for a main body side at a design stage. Accordingly, in the present invention, an increase in size of the main body casing, its design change, etc. can be avoided.

BEST MODE FOR CARRYING OUT THE INVENTION

[0032] Embodiment modes of an information processor according to the present invention will next be explained by using the drawings.

[0033] The information processor in this embodiment mode is a game machine having a function as an entertainment device. As shown in FIG. 1, the information processor has a game machine main body 1, an external storage device 10 stored from an opening 3 of a main body casing 2 of the game machine to the interior thereof, a cover 30 for blocking the opening 3 of the main body casing 2, and a controller 7 operated by a player. In this embodiment mode, the external storage device unit is constructed by including the external storage device 10, the cover 30, respective connectors 40 a, 40 b, 41, 42 described later, and a side face frame plate 20.

[0034] A storing housing 50 for the external storage device, a mother board 4 mounting various kinds of electronic elements, etc. thereto, a cooling fan 5, an unillustrated DVD drive unit for reproducing game software, movie software, etc., an unillustrated power circuit, etc. are arranged within the main body casing 2.

[0035] The external storage device 10 is a hard disk drive (HDD) unit, and stores data such as a game status, a game program, etc. relative to a game. It also stores data from various kinds of broadcasting media, data obtained through the Internet, etc.. As shown in FIGS. 2 and 3, this external storage device 10 has a case 11 mounting a magnetic disk thereinto and approximately formed in a rectangular parallelepiped shape, and a power connector 17 a and a signal connector 17 b as external connection connectors arranged on one face (hereinafter referred to as a front face 12) of the case 11. A portion forming a bottom face of this case 11 is opened, and this opening is covered with a thin insulating sheet 15 (FIG. 3). The insulating sheet 15 is substantially formed in a rectangular shape in conformity with the opening of the rectangular shape, but a backward side of the insulating sheet 15 is notched in a V-character shape.

[0036] As shown in FIGS. 3 to 6, side face frame plates 20 respectively covering side faces 13 a, 13 b are arranged on the case side faces 13 a, 13 b of the external storage device 10. The side face frame plate 20 has a frame plate main body portion 21 of a rectangular shape substantially covering each of the case side faces 13 a, 13 b, an attaching flange 22 and a device front face pressing flange 23 formed in front of this frame plate main body portion 21, a device upper face pressing flange 24 formed above the frame plate main body portion 21, and a device bottom face pressing flange 27 formed below the frame plate main body portion 21. Each flange is formed approximately perpendicularly to the frame plate main body portion 21. However, the device upper face pressing flange 24 is once bent 180° with respect to the frame plate main body portion 21, and is then again turned up 90° in a reverse direction. As a result, the device upper face pressing flange 24 forms 90° with respect to the frame plate main body portion 21. Corners of this frame plate main body portion 21 and the device upper face pressing flange 24 serve as a rail 25 when the external storage device 10 attaching this side face frame plate 20 thereto is stored into the storing housing. A projecting portion 26 projected upward is formed on this rail 25 in an end portion on a forward side and an end portion on a backward side.

[0037] As shown in FIG. 15A, a width Wb of the side face frame plate 20 except for the projecting portion 26 is set to have a length at which the side face frame plate 20 except for the projecting portion 26 is reliably stored into the storing housing 50, and is also set to be slightly shorter than the clearance H of an upper wall face 51 and a bottom wall face 52 of the storing housing 50. An entire width Wa of the side face frame plate 20 including the projecting portion 26 is set to have a length at which an end portion of the side face frame plate 20 including the projecting portion 26 is caught by an opening edge of the storing housing 50 even when the side face frame plate 20 including the projection portion 26 is intentionally stored into the storing housing 50. The entire width Wa is also set to be slightly longer than the clearance H of the upper wall face 51 and the bottom wall face 52 of the storing housing 50. Namely, a projecting amount d of the projecting portion 26 is very small and is set to be equal to or smaller than 0.5 mm in this embodiment mode. In FIGS. 5, 6, 14 and 15A, the projecting amount is relatively largely drawn to clarify the existence of the projecting portion 26.

[0038] As shown in FIGS. 3 and 4, a leaf spring 29 functioning as an elastic member is arranged in one side face frame plate 20 among the two side frame plates 20, 20. In this leaf spring 29, one portion of a metallic plate is formed in an arc shape. Plural spring openings 21 a, 21 a are formed in the frame plate main body portion 21. The leaf spring 29 is attached to the frame plate main body portion 21 such that an arc portion 29 a of the leaf spring 29 is projected from this spring opening 21. In FIG. 4, the device upper face pressing flange 24 is omitted to easily understand the relation of the frame plate main body portion 21 and the leaf spring 29.

[0039] As shown in FIG. 2, the storing housing 50 of the external storage device 10 is formed in a rectangular parallelepiped shape in conformity with an external appearance shape of the external storage device 50. A main body connector 48 for a cover side for transmitting and receiving signals between the external storage device, etc. is arranged in a front end portion of the wall face 51 of this storing housing 50.

[0040] As shown in FIG. 3, the cover 30 has a cover main body 31 made of resin, a base plate 32 fixed to a rear face of the cover main body 31, a circuit substrate 33 fixed to the base plate 32, and an electromagnetic shield cover 34 covering the circuit substrate 33. A power connector 40 afor a storage device side connected to the power connector 17 a of the external storage device 10, and a signal connector 40 b for a storage device side connected to the signal connector 17 b of the external storage device 10 are attached to the base plate 32. A connector 41 for a main body side connected to a cover side main body connector 48 (FIG. 2) arranged within the main body casing 2, a communication connector 42 for external communications, and a communication circuit module 33 a (FIG. 1) for processing transmitted and received signal data through this communication connector 42 are arranged in the circuit substrate 33. For example, it is possible to establish an external communication by using Ethernet or a telephone line. As shown in FIGS. 7 and 8, the communication connector 42 is arranged such that a connecting face of the communication connector 42 is exposed from the surface of the cover main body 31. As shown in FIGS. 8 to 10, the power connector 40 a for a storage device side, the signal connector 40 b for a storage device side, and the connector 41 for a main body side are arranged such that connecting faces of these connectors are exposed from the electromagnetic shield cover 34 on a rear face side of the cover main body 31. The connector 41 for a main body side is electrically connected to the circuit substrate 33 by a cable 59 (FIG. 3). Therefore, the connector 41 for a main body side is electrically connected to the communication connector 42 through the communication circuit module 33 a arranged in the circuit substrate 33. Further, the connector 41 for a main body side is electrically connected to the power connector 40 a for a storage device side and the signal connector 40 b for a storage device side by the cable 59 and wiring formed on the circuit substrate 33. Namely, as shown in FIG. 1, power and signals between the game machine main body and the external storage device 10 are supplied via the cover 30 for blocking the opening 3 for storing the external storage device 10 into the game machine main body 1.

[0041] As mentioned above, in this embodiment mode, as shown in FIG. 1, since the power connector 40 a for a storage device side and the signal connector 40 b for a storage device side are arranged in the cover 30, it is not necessary to secure a space for storing these connectors 40 a, 40 b within the main body casing 2 of the game machine. Further, the position of wiring 6 for connecting the mother board 2 of the game machine and the external storage device 10 can be freely changed by suitably setting the position of the connector 41 for a main body side, in other words, by suitably setting the cover side main body connector 48 connected to this connector 41 for a main body side at a design stage. Accordingly, in this embodiment mode, an increase in size of the main body casing, its design change, etc. can be avoided.

[0042] As shown in FIGS. 3 and 13, the storage device side signal connector is fixed to a connector fixing plate 35. A screw (connecting tool) for attaching this connector fixing plate 35 to the base plate 32 is a shoulder screw 37, and has a screw head portion 37 a,a columnar portion 37 b forming no male screw thereon, and a screw portion 37 c having a screw outside diameter smaller than the outside diameter of the columnar portion 37 b. A screw receiving plate 36 forming a female screw hole 36 a therein is arranged to receive the screw portion 37 c of this shoulder screw 37. This screw receiving plate 36 is arranged such that the base plate 32 is nipped between this screw receiving plate 36 and the connector fixing plate 35. An insertion hole 35 a having an inside diameter approximately equal to the outside diameter of the columnar portion 37 b of the shoulder screw 37 is formed in the connector fixing plate 35. An insertion hole 32 a having an inside diameter larger by about 2 mm than the outside diameter of the columnar portion 37 b of the shoulder screw 37 is formed in the base plate 32. The shoulder screw 37 is screwed into the female screw hole 36 a of the screw receiving plate 36 through the through hole 35 a of the connector fixing plate 35 and the through hole 32 a of the base plate 32. In this case, the columnar portion 37 b of the shoulder screw 37 is located within the through hole 32 a of the base plate 32. As a result, the connector fixing plate 35 and the screw receiving plate 36 can be relatively moved by the difference between the inside diameter of the through hole 32 a of the base plate 32 and the outside diameter of the columnar portion 37 c of the shoulder screw 37 with respect to the base plate 32. Namely, the storage device side signal connector 40 b is arranged relatively movably with respect to the cover main body 31 and the base plate 32. Further, similar to the signal connector 40 b for a storage device side, as shown in FIG. 3, the power connector 40 a for a storage device side is also arranged relatively movably by the connector fixing plate 38, the screw receiving plate 39 and the shoulder screw 37 with respect to the base plate 32.

[0043] A pin interval within the power connector of the external storage device, and a pin interval within the signal connector are generally very accurate, and lie within a very small error range in any maker. Further, layouts of the power connector and the signal connector with respect to the case of the external storage device are basically approximately the same in any maker. However, there are slight differences between the same maker products in the relative position relation of the power connector and the signal connector. For example, there is a difference close to 1 mm between different makers in this relative position relation Therefore, as in this embodiment mode, when the respective connectors 40 a, 40 b connected to the power connector 17 a and the signal connector 17 b are attached to the cover 30 and are fixed to the cover 30, connector connection with the cover can be made with respect to the external storage device of a certain maker, but cannot be made with respect to the external storage device of another maker since there is a relatively large difference between the makers as mentioned above with respect to the relative position relation of the respective external connection connectors 17 a, 17 b of the external storage device 10. Therefore, in this embodiment mode, the power connector 40 a for a storage device side and the signal connector 40 b for a storage device side are attached relatively movably to the cover main body 31. In this embodiment mode, both the power connector 40 a for a storage device side and the signal connector 40 b for a storage device side are attached relatively movably to the cover main body 31, but only one of the power connector 40 a for a storage device side and the signal connector 40 b for a storage device side may also be attached relatively movably to the cover main body 31.

[0044] As mentioned above, as shown in FIGS. 11 and 12, the communication connector 42 having a connection face exposed from the surface of the cover main body 31 has a connector housing 43 made of insulating resin, plural connection pins 44, 44, - - - arranged in this connector housing 43, a magnetic shield material 45 made of a metal and covering one portion of a side face of the connector housing 43 and the connection face, and a resin cover 46 covering the surface of this magnetic shield material 45. Since a surface side of the communication connector 42 in this embodiment mode is thus covered with the magnetic shield material 45, the communication connector 42 is excellent with respect to an electromagnetic obstacle. Further, since the surface of this magnetic shield material 45 is covered with the resin cover 46, the communication connector 42 is also excellent in view of the protection of a finger of a player, etc.

[0045] When the external storage device 10 is used, the external storage device 10 to which the side face frame plates 20, 20 are attached is first pushed into the storing housing 50 within the game machine main body 1 as shown in FIG. 2. In this process, as shown in FIG. 4, the arc portion 29 a of the leaf spring 29 arranged in one side face frame plate 20 comes in contact with one side wall face 53 among the pair of side wall faces 53, 53 of the storing housing 50, and presses the external storage device 10 against a side of the other side wall face 53. Further, as mentioned above by using FIG. 15A, the entire width Wa of the side face frame plate 20 is slightly longer than the clearance H of the upper wall face 51 and the bottom wall face 52 of the storing housing 50. Therefore, in a storing process of the external storage device 10, the projecting portion 26 of the side face frame plate 20 hits against an upper wall face edge of the storing housing 50, and is crushed by plastic deformation. As shown in FIG. 15B, the entire width of the side face frame plate 20 approximately becomes the same as the clearance H of the upper wall face 51 and the bottom wall face 52 of the storing housing 50, and the external storage device 10 enters the storing housing.

[0046] In general, a convex type guide rail is arranged on one of a side face of the external storage device and a side wall face of the storing housing, and a concave type guide rail is arranged on the other to securely store the external storage device into the storing housing, In this method, it is necessary to arrange the guide rails in both side portions of the. external storage device, and a relatively large space is required, between the side face of the external storage device and the storing housing side face. Therefore, the storing housing is large-sized, and it is necessary to precisely process each of the guide rails so as not to cause play so that manufacture cost is increased.

[0047] In contrast to this, in this embodiment mode, the external storage device 10 is pressed against one side wall face 53 of the storing housing 50 and is regulated in position by utilizing elastic force of the leaf spring 29 arranged only in one side portion of the external storage device 10 with respect to the position of the external storage device 10 in its side direction. With respect to the position of the external storage device 10 in its vertical direction, the projecting portion 26 of the side face frame plate 20 is plastically deformed and crushed in the storing process, and comes in close contact with the upper wall face 51 of the storing housing 50 and is regulated in position. Accordingly, no relatively large occupying space is required as in the above guide rail, and it is not necessary to arrange the guide rails in both side portions of the external storage device so that the storing housing can be made compact. Further, in this embodiment mode, manufacturing cost can be restrained since it is not necessary to precisely process the leaf spring 29 and the projecting portion 26 as in the guide rail.

[0048] Further, in this embodiment mode, since the bottom face of the external storage device 10 is covered with the thin insulating sheet 15 (FIG. 3) of high flexibility, there is a possibility that the insulating sheet 15 is caught by any portion of the bottom wall face 52 of the storing housing 50 in a process in which the external storage device 10 is stored into the storing housing 50. Therefore, in this embodiment mode, a backward side of the insulating sheet 15 is notched in a V-character shape, and a rear end side (a front end side when a storing direction of the external storage device 10 is set to a reference) of the insulating sheet 15 is set to be inclined (instead of perpendicular) with respect to the storing direction of the external storage device 10. Thus, even when the insulating sheet 15 begins to be caught by any portion of the bottom wall face 52 of the storing housing 50, the insulating sheet 15 can be easily escaped from this portion.

[0049] When the external storage device 10 is stored into the storing housing 10, the opening 3 of the device main body 1 is closed by the cover 30 as shown in FIG. 2. In this case, as shown in FIG. 14, the cover 30 is guided to the main body side such that the main body side connector 41 attached to the cover 30 is connected to the cover side main body connector 48 fixed to an upper portion of the storing housing 50. In a process in which the main body side connector 41 of the cover 30 is connected to the cover side main body connector 48 of the device main body, the power connector 40 a. for a storage device Bide and the signal connector 40 b for a storage device side arranged in the cover 30 are respectively relatively moved with respect to the cover main body 31, and are connected to the power connector 17 a and the signal connector 17 b of the external storage device 10 in conformity with these connector positions. Thus, in the process in which the main body side connector 41 of the cover 30 is connected to the cover side main body connector 48 of the device main body, the power connector 40 a for a storage device side and the signal connector 40 b for a storage device side arranged in the cover 30 are respectively moved with respect to the cover main body 31 so as to be in conformity with the positions of the power connector 17 a and the signal connector 17 b of the external storage device 10. This is because it is constructed such that the outside diameter of a tip portion of a pin arranged in one of the connectors connected to each other is gradually reduced toward a tip side, and the inside diameter of a tip portion of a hole formed in the other connector is gradually increased toward the tip side, and shapes of the tip portion of the pin and the tip portion of the hole function as guides convenient in mutual position alignment and the pin is reliably stored into the hole even when positions of the pin and the hole are slightly shifted from each other. Further, this is also because the shapes of both connector housings similarly function as the guides convenient in the mutual position alignment.

[0050] As shown in FIG. 14, when the main body connector 48 for a cover side in the device main body and the connector 41 for a main body side in the cover 30 are connected, and the power connector 40 a for a storage device side and the signal connector 40 b for a storage device side in the cover 30 are respectively connected to the power connector 17 a and the signal connector 17 b of the external storage device 10, a cover fixing screw 49 is inserted into a screw hole 31 a formed in the cover main body 31 as shown in FIG. 2. A screw portion on a tip side of this cover fixing screw 49 is screwed into a screw hole 55 a of the storing housing 50 through a screw hole 22 a of the side face frame plate 20, and the cover 30 and the external storage device 10 are fixed to the device main body 1.

[0051] In a personal computer, etc. as a general information processor, the external connection connector of the external storage device is designed such that, when a connector is once connected to this external connection connector, this connector is not basically disconnected from the external connection connector after this connection. In contrast to this, in this embodiment mode, a case in which only the external storage device 10 is detached from the device main body 1 and is attached to e.g., another game machine main body, etc. might be also caused. Namely, in this embodiment mode, the number of inserting and pulling times of the external connection connectors 17 a, 17 b of the external storage device 10 is increased, and there is a fear of a reduction in connection performance of the external connection connectors 17 a, 17 b. Therefore, as shown in FIG. 16, a relay connector 47 not reduced so much in the connection performance even when the number of inserting and pulling times is increased, is preferably arranged between the external connection connector 17 a and the connector 40 a for a storage device side in the cover 30. It is also preferable that inserting and pulling operations are performed between this relay connector 47 and the connector 40 a for a storage device side in the cover 30, and are basically not performed between the relay connector 47 and the external connection connector 17 a.

[0052] In the above embodiment modes, the present invention is applied to the game machine, but is not limited to this case. For example, the present invention may also be applied to a personal computer as one kind of a general information processor. The external storage device 10 in the above embodiment modes is a hard disk drive unit mounting a magnetic disk thereto, but may also be an external storage device mounting another memory medium thereto.
